Q

where is coA used

A

link reaction - combines with acetate to form acetyl coa
krebs cycle - deliveres acetyl group to oxaloacetate forming citrate

Q

whats the fate of FAD

A

carriers electrons to the ETC
enters later in ETC than NADH - producing less ATP

Q

fate of NADH

A

delivers electeons to the ETC, reoxidised back to NAD so can be reused

Q

when does NAD become reduced

A

hydrogen atoms form glycolysis , link reaction + krebs cycle
electrons carried with those hydrogens
